LQOIVl-SHUTTLE.

SPECIFICATION forming part of Letters Patent N 0. 558,753, dated April21, 1896.

Application filed July 22, 1895- Ta on whom it may concern:

Be it known that I, JOHN ALLEN, a citizen of the United States, residingat Paterson, in the county of Passaic and State of New Jersey, haveinvented certain new and useful Improvements in Loom-Shuttles; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to loom-shuttles, and is directed moreparticularly to improvements in that class of shuttles which areemployed in the operation of silk-weaving.

The invention has for its object the production of a shuttle havingmeans, in the nature of two cops or bobbins, for deliveringsimultaneously two threads, and also having means of a new and novelnature for separating and insuring the separation to the point ofweaving of the two threads delivered from the cops or bobbins, with theresult to entirely preclude any contact thereof until the proper time,thereby preventing any twisting and tan gling of the threads andinsuring the proper operation and a perfect weave.

In the class of weaving referred to-namely, that of silk-it has been thepractice heretofore to employ a separate shuttle for each thread, and,while the use of the extra shuttle is in itself costly, the greatestexpense attending the previous operations was in the necessaryemployment of a 100m of the box type. In practicing my invention,however, I employ what is termed a plain loom, the cost of which is butone-third of the cost of the box-loom referred to, and this advantagealone, irrespective of the increased capacity and improved productresulting from its use, places my invention in advancement of the priorart.

The nature of my invention will fully appear by reference to thefollowing description when taken in connection with the accompanyingdrawings, in which Figure 1 is a plan view of my improved shuttle. Fig.2 is a side elevation partly broken away. Fig. 3 is a sectional view online cc :0

of Fig. 1, and Fig. 4 is a sectional view on line y y of same figure.

Referring to the said drawings by letter, A denotes the shuttle-body,provided with the usual recess a, but which is made of sufficient lengthto accommodate two bobbins B B, which are mounted on tongues pivotallyarranged. The said bobbins lie in position end to end and deliver thethreads centrally of the shuttle, at which point the body is providedwith a thread-delivery eye 0, preferably vertically arranged in anenlargement or of one of the side walls of the body, said eye beinglocated centrally between the ends of the shuttles, but to one side ofthe line thereof. Secured to one side of the shuttle is a semicircularguard cl, and a strip e is interposed between the side of the bodyandthe guard to serve as a means for holding rigidly two thread-tubes f g.Said tubes are lined with porcelain or other material, and at theirinner ends extend to a point in line with the bobbins. The tube fextends to and through the guard; but the tube 9 terminates shortthereof, and, if desired, said tubes are firmly secured together bysoldering. In threading the shuttle the thread b from the bobbin B ispassed directly through the tube f, being thereby delivered at apointsome distance from the body of the shuttle. The other thread, I),of the bobbin B is first passed through the tube g, and from thence toandthrongh the eye 0, the point of its deliverybeing thereby within theside of the shuttle adjacent to the point of delivery of the thread 17and same distance from the latter. By this means the threads are notonly fed or delivered in a separated condition, but the separation ismaintained by reason of the initial distance between the points ofdelivery until the weaving actually takes place. There is no contactuntil the threads are in the cloth, and hence there is no twisting nortangling, as would be the case were the threads delivered from the sameeye. This result in silk-weaving was heretofore attainable only by theemployment of a separate shuttle for each thread, which alsonecessitated a boxloom. In the present case the much cheaper plain loomis employed, and the cost of weaving is thereby greatly reduced.

My improved shuttle, while capable of application to weaving generally,is especially adapted to the weaving of silk fabrics, and generally tothat class of silk fabrics which may be designated as changeable,iridescent, or chameleon, such fabrics being generally composed of threethreads of differing colors, one of said threads constituting the warpand the other two the filling threads. To produce the optical effectpeculiar to this kind of silk fabrics, the fillingthreads arenecessarily woven in parallel relation and have a regular and uniformalternation of color. This effect has been previ ously accomplished bythe use'of two separate shuttles in a loom of the box type, as beforestated, the employment of said separate shuttles being necessary toavoid the twisting, mixing, or tangling of the two threads, theoccurrence of which, even in a slight degree, is fatal to the peculiareffect described. By my invention the extra shuttle is dispensed with,and consequently I am enabled to employ in the operation a loom of theplain type. My improved shuttle having two bobbins which feedsimultaneously two filler-threads at the point of delivery from theshuttle in sures the same result as that attained by the employment ofthe two separate shuttles in the box-loom.

Aside from the great economy incidental to the use of the plain loom ascompared with the use of the box-loom, the extra shuttle is dispensedwith and the output of the 100111 is greatly increased. Moreover, I amenabled to attain by the performance of my invention an improvedproduct, owing to the maintenance of parallelism of the filling-threadsthroughout the body of the fabric and the consequent regular and uniformalternation of color. In addition to these advantages the plain type ofloom employed by me is more readily controlled and can be operated atless expense than a loom of the box type.

, I claim as my invention- 1. A shuttle having a plurality of bobbinsand a guard connected to and extending beyond the side thereof, a guidein the body of the shuttle for delivering a thread at said body, and aguide extending from the body to the guard for delivering a threadbeyond the latter to provide the maximum separation of said threads.

2. A shuttle having two bobbins arranged end to end, and having in oneof its sides a thread-delivery eye and an opening below said eye, acurved guard connected to and extending beyond said side, a thread-tubepassed through the said side and projecting into the interior of theshuttle and extending through said guard to provide a thread-deliverypoint at the maximum distance from the shuttle, and a second thread-tubeopening into the interior of'the shuttle and extending beyond theoutside thereof but within the guard, and forming with the opening andeye a second thread-passage.

3. In a shuttle, the combination of two bobbins arranged end to end, theside wall provided with an enlargement and a transverse openingtherethrough, a thread-delivery eye vertically arranged in saidenlargement, the guard secured to and extending centrally beyond saidside wall and a plate interposed between said guard andwall, and twothreadtubes secured in said plate, both of which extend within theinterior of the shuttle, one terminating within the guard and the otherterminating without the guard, whereby one thread is delivered at thesaid wall and the other at a point beyond the guard, substantially asand for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.JOHN ALLEN.
